State Route 54 (SR 54) is a state highway in San Diego that connects Interstate 5 to the city of El Cajon. The first section was built circa 1961, and the final section of freeway (which was upgraded from an expressway) opened in 2007.

Route description[edit]

SR 54 starts as a freeway from I-5 at the mouth of the Sweetwater River in National City, with westbound traffic traversing the north bank of the river and eastbound traffic traversing the south bank. Both sides join near the junction with I-805 and continue east for several miles through Paradise Hills in San Diego. As the freeway turns north, it merges with SR 125 north, and SR 54 exits at Jamacha Boulevard in La Presa. SR 54 follows Jamacha Boulevard northeast through Spring Valley until reaching Campo Road, although some maps only sign Jamacha Boulevard as County Route S17 (CR S17), and Caltrans does not recognize this as part of SR 54.[2][3][4]

SR 54 then runs concurrently with SR 94, following Campo Road about 0.5 miles (0.80 km) east. SR 54 and CR S17 continue northeast on Jamacha Road to El Cajon, while Campo Road and SR 94 split off to the southeast. SR 54 currently ends at the El Cajon city limit, though the Jamacha Road street name continues into the city to the route's previous terminus at the intersection with I-8.[2][3][5][1]

SR 54 is part of the California Freeway and Expressway System,[6] but is not part of the National Highway System (though SR 125 is),[7] a network of highways that are essential to the country's economy, defense, and mobility.[8] The route has the three different names given by various state laws, including Jamacha Road from Campo Road to East Main Street in El Cajon, South Bay Freeway from I-805 to SR 94, and Filipino-American Highway from the western terminus to SR 125.[9][10]

In 2012, SR 54 had an annual average daily traffic (AADT) of 22,900 at the eastern end of the route, and 126,000 between I-805 and Reo Drive, the latter of which was the highest AADT for the highway.[4]


The South Bay Freeway east of I-805

In 1959, the California State Legislature added a route from near the Sweetwater River to El Cajon.[11] SR 54 was officially designated in the 1964 state highway renumbering.[12]

Route 54 first opened between Sweetwater Road (at the site of present day North 2nd Avenue in Chula Vista) and Jamacha Boulevard in Spring Valley. The South Bay Freeway was constructed as a freeway only between its western terminus and Reo Drive, a short distance west and east of the I-805 junction, with the remainder built as an expressway.

Route 54 was extended west as a freeway to I-5 at the same time the Sweetwater River flood control channel was constructed in the early 1990s.[citation needed] The expressway portion from Reo Drive to South Worthington Street was upgraded to a freeway in the late 1990s, and a HOV lane opened in each direction, east of I-805 only, around this time.[5]

The state legislature allowed for the relinquishment of SR 54 from the El Cajon city limit to I-8 to the City of El Cajon in 1999.[13]

The remaining expressway portion of Route 54, running from South Worthington Street to Jamacha Boulevard, was replaced by a freeway in two phases in the 2000s. The first phase corresponded with construction of Route 125 north of Jamacha Boulevard and was completed in 2003. The second phase corresponded with construction of the South Bay Expressway toll road and was completed in 2007. The HOV lanes were converted to regular mixed traffic lanes shortly thereafter.

Major intersections[edit]

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in San Diego County.
